Avionics Wiring Continued

Time: 4 hrs

Over the past fews days I finished up most of the wire runs for the avionics that I’m mounting on the shelves and rib. I also terminated all the grounds to the main grounding block. I’ve been trying to understand the way Garmin has set up the grounds on the avionics. It seems like most of them have redundant grounds. I’m not sure if it’s just for redundancy or if they actually need to be connected to function properly. It seems like a few actually do need the multiple grounds connected like in the case of the transponder, but most seem to be merely for redundancy. I’m planning on only doing redundant grounds on the “essential” equipment since I’ll probably run out of connections on my ground bus.

I’m going to get the connector kits for some of the avionics so I can start wiring them up. I don’t have the money right now to get all the avionics that I need so with the foam mockups and the connectors I should be able to get everything wired up. When I do get the avionics it should go very quick getting them installed.

I’m also wondering if I need to wire in connectors for the avionics that will be mounting to the instrument panel. It seems like it would be good to do so that the whole panel could be more easily removed, but I don’t want to add in more potential points of failure. I guess I’ll need to think about it a bit more.
